Abstract: Embodiments of this application provide an encoding method, a decoding method, and an electronic device. The method includes: obtaining a current frame; obtaining a reconstructed picture corresponding to a reference frame of the current frame from an external reference list of an encoder, where the reference frame of the current frame is a frame encoded by the encoder, and the external reference list is independent of the encoder; performing, by the encoder, intra coding on the reconstructed picture; and performing, by the encoder, inter coding on the current frame based on a result of the intra coding, to obtain a bitstream corresponding to the current frame. In this way, the encoder may flexibly select a reference frame from the external reference list for encoding, thereby implementing cross-frame reference or cross-resolution reference, and improving flexibility of reference frame management of the encoder.
